Definitions
- the present invention provides an advantage over the known arrangements by providing means for the transferral of electric power and/or signals between two elements rotating in relation to each other, which elements for instance may be a vessel and an underwater installation and is concerned particularly, although not exclusively, with a system for transferring electrical power in a turret-moored vessel.
- the channel extends around the circumference of the housing.
- the housing is preferably suspended from a support structure mounted on the vessel.
- the support structure preferably extends along the length of the housing.
- the seal means preferably comprises an internal seal member and an external seal member.
- the slip-ring arrangement preferably comprises damping means to restrict minor movements of the slip-ring arrangement.
- the damping means preferably comprises a torque assembly mounted to the slip-ring arrangement.
- the torque assembly preferably connects the bush carrier to the turret.
- Figure 19 is a top perspective view of the turret, the swivel and the support track for the slip-ring housing and shows the assembly of part of the housing using a crane;
- Figure 20 is a side perspective view of the turret, the swivel and the support track for the slip-ring housing;
- Figure 24 is a section view through AA
- the support structure 6 is formed with three tubular column sections l la, l ib, l ie. Disposed at the top of section 1 Ia is a cantilever crane 12.
- the housing 4 of the EPSR system 3 has a relatively large diameter slip-ring compared to existing solutions. Typical range of large diameter slip-ring systems are in the region from 2.05 meters up to 15 meters.
- the current load may be very low, and the current rating can easily be increased.
- the LV rings are located in the top section of the EPSR system 3, with the rings fixed to the housing 4 and the brushes fixed to the carrier 8.
- the cables will be routed to an external LV junction box, with intermediate cables into the LV rings inside the EPSR system 3. From the LV brushes on the carrier 8, intermediate cables are routed to an external junction box located on the turret 2. From these junction boxes cables are routed to the different consumers on the turret 2.
- the main purpose of the slip-ring housing 4 is to:
- the main purpose of the slip-ring internals 14, 15 are: • Provide a transfer of electrical power (and signals) independent of vessel movement's vs. the turret 2, from the vessel-side to the turret 2.
- the main purpose of the brush carrier 8 is to: • Provide a connection/feed-through to the turret 2 side high voltage power cables and low voltage supply cables.
- the total EPSR system 3 is hanged up in the gantry support tract 22 by three support bearings 24a, 24b, 24c.
- the bearings 24a, 24b, 24c are of pin type free to rotate in x- and Y directions.
- the EPSR loads are transferred via the guide rails/bearings and fastening clamp into a web on the supporting girders.
- the sealing system between ambient and slip-ring system 3 internals is an important part of the EPSR system 3 requirement.
- the present invention may comprise one of two different types of sealing solutions.
- the first type of seal arrangement is based on a seal 17 (See Figures 10 and 12) that is in sliding contact with against a plate 19 which is arranged within the channel 5 of the housing 4 around the whole periphery.
- This plate 19 extends around the circumference of the channel 5 and therefore the housing 4.
- the plate 19 is fastened to the brush carrier 8 which holds the brush arrangement, and is stationary in relation to the turret 2.
- the seals 17 are mounted on the rotating house.
- the plate 19 must have steering and guides (with rollers or other mechanisms) to ensure that the disk is not jammed when the ship is rotating.
- the first type of seal arrangement of the sealing system may comprise an external seal 17 and an internal seal 18 in sealing contact with a plate 19.
- the internally over pressurized sealing system should prohibit any gas to enter into the internals of the high voltage environment.
- An external seal is included to ensure that wind loads / other environmental conditions will not influence the internal sealing action.
- the alternative sealing system is based on seals which are abutting each other in the whole of the aperture of the house around the whole of the periphery.
- the carrier 8 which holds the brush arrangement will run in the channel 5.
- the carrier 8 will be stationary in relation to the turret 2.
- the carrier 8 will therefore open the seal in a small sector given by the length of the carrier 8.
- the alternative sealing system (see Figures 12 and 13) comprises a pair of slidable seal members 44, 45 and respective compressive springs 46, 47.
- the seal members 44, 45 extend around the circumference of the channel 5.
- FIG. 12a and 12b there is shown a further alternative sealing assembly comprising a pair of resiliently compressive seal members 60, 61.
- the seal members 60, 61 extend around the circumference of the channel 5.
- the seal members 60, 61 are urged in a direction towards each by their resilient characteristics.
- the leading edge 20 of the carrier 8 moves apart the distal ends of each member 60, 61 and two respective side seal plates 49, 50 force back a portion of the members 60, 61 and the seal members 60, 61 are forced away from each other and flex outwards (see Figure 12a).
- a further alternative sealing assembly comprising a pair of resiliently compressive seal members 70, 72, which extend around the circumference of the channel 5.
- the seal members 70, 72 each comprises a pair of flexible limbs 74, 75, 76, 77.
- the respective distal ends of each limbs 74, 75 is in contact with the corresponding distal end of the limbs 76, 77 (see Figure 14b).
- the seal members 70, 72 are urged in a direction towards each other by their resilient characteristics.
- the EPSR system 3 is designed for easy handling during installation offshore. Therefore the housing 4 (complete with electrical equipment) and the support track 22 are divided into sections for easy handling during offshore assembly.
- the system 3 includes the following items:
- installation of the present invention may be a retro-fit on an existing turret and vessel arrangement or alternatively it may be assembled as part of a new turret and vessel fabrication.
